Which of the following activities performed by a database administrator (DBA) should be performed by a different person?

A. Deleting database activity logs

B. Implementing database optimization tools

C. Monitoring database usage

D. Defining backup and recovery procedures

Explanation:

Since database activity logs record activities performed by the database administrator (DBA), deleting them should be performed by an individual other than the DBA. This is a compensating control to aid in ensuring an appropriate segregation of duties and is associated with the DBAs role. A DBA should perform the other activities as part of the normal operations.
